Lens adjustment
These cameras are equipped with a motorized lens with autofocus. For effective license plate
capture it is essential that the lens is perfectly adjusted. The adjustment is made by connecting
to the browser, as explained in the previous chapter.
Initially press the ZOOM IN / OUT button and adjust the width of the frame
(wide angle / zoom) according to the area to be framed.
Remember that the greater the wide angle, the less image detail inevitably corresponds.
Generally it is good to frame as narrow a width as possible around the position where the license
plate will be so that it appears as large as possible in the frame.
These cameras can frame up to 3 lanes at the same time.
Once the field of view has been defined, focusing will take place automatically. Eventually you can
also act further on the FOCUS button to manually refine the focus on the framed area.
Remember that each lens has its own depth of field so that only a portion of the space in front of
the camera can be perfectly focused. Focus on the area of greatest relevance where the vehicle's
license plate will be to adjust the focus to the optimum. Make sure you have as large a monitor
as possible to be able to assess the quality of detail well.
For a correct adjustment of the lens it may be useful to position a stationary car in the exact point
where the license plate is read. This adjustment should be done in night vision, where conditions
are worst.
